when pounding a girl from the back, you sit an ashtray on her back, so you have somewhere to rest your smokes. it's common courtesy, as otherwise, you would be ashing your cigarette on her back, and that would just be inappropriate

wait baby, don't move. I got to get my ashtray before I take you to the doggystyle pound town

1. A tray for storing ash.
2. A person who smells like a tray for storing ash.
3. The coolest person to ever exist, blessed the Earth with his prescence almost 15 years ago, and to this day he wonders what this planet would do without him.

1. "I'm a cancer-ridden scumbag, pass me my ashtray."
2. "STOP SMELLING YOURSELF..." "I smell like an Ashtray."
3. "Hey, you know Ashtray?" "Yeah. That guy who's the best guitar player at our school, controller of the universe, and future Prime Minister of the World?" "Yeah, him. I heard that his new band is going to rule." "Of course it will, he's in it." "Well, I'm out, I'm going to masturbate to this picture of Ashtray I found." "Shit yeah, negro!"
